Electronic Device For Re-Ordering Items

ABSTRACT

In some cases, a method may include receiving electricity usage data from a re-ordering device and determining usage information for an appliance that is electrically connected to the re-ordering device based on the electricity usage data. The method may also include determining, based on the usage information and order history information for a customer, an estimated remaining quantity of an item that is associated with an appliance type of the appliance. The method further includes comparing the estimated remaining quantity of the item to a threshold associated with the item. In response to determining that the threshold associated with the item is satisfied, the method includes decrementing the estimated remaining quantity of the item. In response to determining that the threshold associated with the item is not satisfied, the method includes generating order data for automated re-ordering of the item for delivery to the customer.

BACKGROUND

Keeping track of ongoing shopping needs may be challenging. For example, shoppers may forget to purchase items and may not realize that they forgot to purchase certain items until after returning from a shopping trip. Further, some shoppers may consider shopping for particular types of household items (e.g., laundry detergent) as “drudgery shopping” and may prefer to focus on the “fun part” of shopping, such as shopping for ingredients for a new recipe.

DETAILED DESCRIPTION

This disclosure describes, in part, techniques and arrangements for determining whether to automatically re-order and schedule delivery of one or more items to a customer based on electricity usage data received from a re-ordering device that is located at a customer premises and that monitors electricity usage for a particular appliance.

In some embodiments, the re-ordering device of the present disclosure may be a separate device installed between an electrical outlet and an appliance (e.g., a washing machine). The re-ordering device may monitor electricity usage by the appliance over time and may store electricity usage data in a memory. In some cases, the electricity usage data may be sent at regular intervals to a remote computing device (e.g., associated with a delivery service) via the customer's Wi-Fi (or similar wireless connection) and the Internet, for further processing.

Upon receipt of the data by the remote computing device, one or more algorithms may be used to process the electricity usage data to determine an appliance type (e.g., a washing machine, a dryer, a dish washer, an oven, etc.) and to estimate the user's consumption of associated products. To illustrate, in the case of a washing machine, laundry detergent may represent a product that may be directly associated with use of the washing machine. Examples complementary products may include fabric softener for use in the washing machine itself or dryer sheets for use in a separate appliance that is associated with use of the washing machine (e.g., a dryer). As an illustrative, non-limiting example, electricity usage data indicative of a single use of the washing machine may represent an estimated consumption of an amount of laundry detergent that is associated with one load of laundry. Further, as a person typically uses a dryer after using the washing machine, the single use of the washing machine may serve as a proxy indicator of consumption of one dryer sheet. As another illustrative example, when the appliance is a single-serving coffee maker that uses disposable coffee cups, electricity usage data indicative of a single use of the coffee maker may represent an estimated consumption of one disposable coffee cup. Further, as some people use coffee creamer and/or sweetener to flavor their coffee, the single use of the coffee maker may serve as a proxy indicator of consumption of one serving of creamer and/or one serving of sugar or another sweetener.

In some cases, past ordering history information for the customer along with calculated consumption data may indicate that particular product(s) are to be flagged for reorder. In some embodiments, the product(s) may be automatically scheduled for delivery to the customer's home or business. Alternatively, suggestions may be placed in the customer's virtual shopping cart or notifications may be sent to the customer, among other alternatives. Thus, the present disclosure describes an electronic feedback system that may initiate product re-ordering without direct user interaction.

Referring to FIG. 1, an example framework 100 for a delivery service that receives electricity usage data from a re-ordering device 102 located at a home or business of a customer is illustrated. In the particular embodiment illustrated in FIG. 1, the re-ordering device 102 is a separate device that is installed between an appliance 104 (e.g., a washing machine in the example illustrated) and an electrical outlet 106. In alternative embodiments, one or more components of the re-ordering device 102 may be included in the appliance 104, a power cord of the appliance 104, or the electrical outlet 106 itself (see e.g., FIG. 5), among other alternatives. As an illustrative, non-limiting example, the power cord of the appliance 104 may include a memory to store information that identifies an appliance type of the appliance 104.

In the illustrative example of FIG. 1, the re-ordering device 102 includes one or more electricity usage components 108 and a memory 110 to store at least electricity usage data 112 and communication data 114. The re-ordering device 102 may correspond to a wide variety of electronic devices. In some embodiments, the re-ordering device 102 may be a computing device that includes one or more processors (e.g., the microcontroller 312 of FIG. 3), and the memory 110 may contain software applications executed by the microcontroller. Software of the re-ordering device 102 may include components for establishing communications over wireless or wired communication networks or directly with other computing devices.

The re-ordering device 102 further includes one or more communication interfaces 116 to communicate with one or more computing devices 118 associated with a delivery service. The one or more computing devices 118 of FIG. 1 include electricity usage processing capabilities as well as customer and item identification processing capabilities. The one or more computing devices 118 can include several devices physically or logically grouped together. In multi-device implementations, the various devices may communicate via an internal communication network, such as a corporate network configured as a local area network (“LAN”) or a wide area network (“WAN”). In some cases, the devices may communicate over an external network, such as the Internet, or a combination of internal and external networks. In further embodiments, the features and services may be provided by one more virtual machines implemented in a hosted computing environment. The hosted computing environment may include one or more rapidly provisioned and released computing resources, which computing resources may include computing, networking and/or storage devices. A hosted computing environment may also be referred to as a cloud computing environment.

In some embodiments, the one or more communication interfaces 116 of the re-ordering device 102 may support at least a wireless connection to various networks, such as a WiFi network. Further, in some cases, the one or more communication interfaces 116 may support both wired and wireless connections to various networks, such as cellular networks, radio, WiFi networks, short-range or near-field networks (e.g., Bluetooth®), infrared signals, local area networks, wide area networks, the Internet, and so forth.

In some cases, the re-ordering device 102 may have access to the Internet via a WiFi connection, or via a cellular telephone network (e.g., a Long Term Evolution or LTE network). In the example of FIG. 1, the re-ordering device 102 may have access to the Internet via a wireless connection with a wireless access point (WAP) 120, which may be connected to a network 122 (e.g., the Internet) via a wired connection (e.g., via a cable modem or a digital subscriber line (DSL) modem, among other alternatives).

The network 122 may be a publicly accessible network of linked networks, possibly operated by various distinct parties, such as the Internet. In other embodiments, the network 122 may include a private network, personal area network (“PAN”), LAN, WAN, cable network, satellite network, etc. or some combination thereof, each with access to and/or from the Internet. For example, the one or more remote computing devices 118 may be located within a single data center, and may communicate via a private network as described above.

The re-ordering device 102 may be configured to communicate the electricity usage data 112 to the one or more remote computing devices 118. Further, the re-ordering device 102 may be configured to communicate one or more identifiers (e.g., at least one of a customer account identifier or a device identifier) to the one or more remote computing devices 118. While not shown in the example of FIG. 1, in some cases the identifier(s) may be stored in the memory 110 (see e.g., FIG. 3).

In the embodiment illustrated in FIG. 1, the one or more computing devices 118 include an analysis module 124, a customer module 126, and a re-order module 128. As described further below with respect to FIG. 2, the analysis module 124 may be configured to determine an appliance type of the appliance 104 based on a comparison of the electricity usage data 112 received from the re-ordering device 102 to a plurality of signatures stored in an electrical signature database 130.

The customer module 126 may be configured to identify a customer associated with the re-ordering device 102 by querying a customer database 132 based on device/customer data received from the re-ordering device 102. The customer database 132 may also contain information with respect to purchase history for various items for the customer. The customer module 126 may be further configured to query an item database 136 to determine information associated with one or more items that may be appropriate for automatic re-order based on the customer's purchase history and the identified appliance 104. The re-order module 128 may determine whether to re-order the item(s) and may communicated associated order data 138 to one or more computing devices 140 associated with an order fulfillment center 142 (e.g., a warehouse). FIG. 1 illustrates that a delivery vehicle 144 may travel from the fulfillment center 142 to a home or business of the customer, and a delivery driver 146 may deliver the automatically re-ordered item(s) 148.

To illustrate, as described further below with respect to FIG. 2, the analysis module 124 may identify the appliance 104 as a washing machine based on a comparison of the electricity usage data 112 received from the re-ordering device 102 and the signatures stored in the electrical signature database 130. The customer module 126 may query the customer database 132 to determine order history information for the customer and may query the item database 136 to determine information associated with one or more items that are applicable to a washing machine appliance type. The re-order module 128 may determine, based on the order history information, whether to automatically re-order one or more of the items.

Referring to FIG. 2, an example framework for communicating electricity usage data from the re-ordering device 102 to a delivery service for analysis is illustrated and generally designated 200.

FIG. 2 illustrates that the electricity usage data 112 stored in the memory 110 of the re-ordering device 102 may include first electricity usage data 202 associated with a first time (identified as “Time(1), On” in FIG. 1), second electricity usage data 204 (identified as “Time(2), Off” in FIG. 1), up to an Nth electricity usage data 206 (identified as “Time(N), On” in FIG. 1).

The re-ordering device 102 may communicate the electricity usage data 112 to the analysis module 124 via the network 122. The analysis module 124 may access the electrical signature database 130 for comparison of the electricity usage data 112 to a plurality of signatures 208. In the example illustrated in FIG. 2, the plurality of signatures 208 includes a first signature 210 (identified as “Signature(1)” in FIG. 2), a second signature 212 (identified as “Signature(2)” in FIG. 2), up to an Nth signature 214 (identified as “Signature(N)” in FIG. 2).

In the example illustrated in FIG. 2, the first signature 210 represents an illustrative, non-limiting example of an electrical signature that may be associated with a washing machine. For example, the graph associated with the first signature 210 identifies power consumption (e.g., in Watts) on the Y-axis and time (e.g., in seconds) on the X-axis. The graph associated with the first signature 210 illustrates that this type of appliance has two distinct sections: a main cycle 216 and an end section 218. For example, the main cycle 216 may be between 10 and 30 minutes in duration, with a substantially constant power draw of about 2000 W. The end section 218 may be longer in duration, with an alternating power draw of either about 200 W or 0 W.

By contrast, the second signature 212 represents an illustrative, non-limiting example of an electrical signature associated with a dishwasher. For example, the graph associated with the second signature 212 illustrates that this type of appliance has four distinct sections: a first main wash 220 (identified as “Main Wash(1)” in FIG. 2), followed by a first idle period 222 (identified as “Idle Period(1)” in FIG. 2), a second main wash 224 (identified as “Main Wash(2)” in FIG. 2), followed by a second idle period 226 (identified as “Idle Period(2)” in FIG. 2). A duration of the first main wash 220 may be about 25 minutes, while a duration of the second main wash 224 may be about 30 minutes, during both of which a substantially constant power of about 1600 W is drawn. The first idle period 222 may have a duration of about 20 minutes, during which a substantially constant power of 50 W is drawn. The second idle period 226 may have a shorter duration of about 5 minutes, during which a substantially constant power of 50 W is drawn, gradually tapering to 0 W.

By comparing the electrical usage data 112 received from the re-ordering device 102 to the plurality of signatures 208, the analysis module 124 may determine an appliance type 228. For example, the analysis module 124 may determine that the electrical usage data 112 substantially matches the first signature 210 and determine that the appliance type 228 is a washing machine (as illustrated in the example of FIG. 1).

The analysis module 124 may provide the appliance type 228 to the customer module 126. The customer module 126 may access the customer database 132 to determine order history information 230 associated with the customer. In the illustrative example of FIG. 2, the order history information 230 is simplified to illustrate at least one item 232 that is associated with the identified appliance type 228. Further, the order history information 230 may include a date 234 (or other time) that a particular item was most recently ordered by the customer, along with other item information, such as a size 236, that may be useful in estimating whether a re-order is appropriate for the particular item.

As an illustrative example, when the appliance type 228 includes a washing machine, a first item may include laundry detergent 238. FIG. 2 further illustrates an example in which another item may be associated with the customer doing the laundry but may not be used by the washing machine itself. To illustrate, the second item shown in the example of FIG. 2 includes dryer sheets, which may not be used by a washing machine but rather by a dryer.

Referring to FIG. 3, an exploded view of select components of the example re-ordering device 102 of FIGS. 1 and 2 is illustrated and generally designated 300.

In the example illustrated in FIG. 3, the re-ordering device 102 includes a plug 302, a socket 304, and a power supply pass-through 306 to provide power to one or more internal components of the re-ordering device 102. Alternatively, a battery or other power source may be used to provide power to the internal components of the re-ordering device.

In the particular embodiment illustrated, the re-ordering device 102 includes a load current shunt resistor 308 disposed between the plug 302 and the socket 304. A voltage drop measurement module 310 is electrically coupled to an input to the load current shunt resistor 308 in order to measure an input voltage (identified as “V(in)” in FIG. 3) and to an output of the load current shunt resistor 308 in order to measure an output voltage (identified as “V(out)” in FIG. 3). It will be appreciated that the load current shunt resistor 308 is merely one illustrative example of measuring a current and/or a voltage. A shunt resistor is based on Ohm's law that an amount of voltage generated across the shunt is directly proportional to an amount of current that is flowing through the load. In alternative embodiments, a current transformer or a Hall effect sensor may be employed, with both alternatives based on the fact that for a given current flow, a proportional magnetic field is produced in accordance with Ampere's law.

The re-ordering device 102 also includes a microcontroller 312. In a particular embodiment, the microcontroller 312 may include an embedded processor with embedded memory (e.g., a 1 MB Flash memory) and static random-access memory (SRAM), such as a 128 KB static SRAM. In the example illustrated, a power supply 314 receives power via the power supply pass-through 306 and includes an alternating current (AC) to direct current (DC) converter 316 in order to provide direct current (e.g., 3.3V) to the microcontroller 312. Further, the microcontroller 312 is electrically coupled to the voltage drop measurement module 310, a timing module 318, and a wireless module 320 (e.g., a Wi-Fi module) which is electrically coupled to an antenna 322. FIG. 3 further illustrates that the microcontroller 312 may be communicatively coupled to the memory 110 (e.g., a serial flash memory) and a wireless module 320 (e.g., a Wi-Fi module).

In a particular embodiment, the wireless module 320 may include hardware, such as an Institute of Electrical and Electronics Engineers (IEEE) 802.11b/g/n single band (e.g., 2.4 GHz) radio that may communicate via a single antenna (e.g., the antenna 322). In some cases, the wireless module 320 may have a maximum transmission (Tx) power of about +19 dBm (CCK) for 802.11b communications, a maximum Tx power of about +18 dBm (11g OFDM) for 802.11g communications, and a maximum Tx power of about +18 dBm (11n MCSO) for 802.11n communications.

The wireless module 320 may be activated to establish a wireless connection (e.g., with a wireless access point (WAP) of the user). In some cases, the microcontroller 312 may be configured to activate the wireless module 320 in order to establish a wireless connection with a particular WAP based on connection information that may be stored in the memory 110. For example, a service set identifier (SSID) 328 and an (optional) password 330 associated with the particular WAP (e.g., the WAP 120 in FIG. 1) may be stored in the memory 110 and may be used to establish the wireless connection. After establishing the wireless connection, information stored in the memory 110 (e.g., at least a portion of the electrical usage data 112, a device/customer identifier 332, or combination thereof) may be communicated to a delivery service for processing.

The voltage drop measurement module 310 is configured to measure a voltage drop 324 (illustrated as “ΔV” in FIG. 3) across the load current shunt resistor 308 that is associated with electricity usage by an appliance (not shown) that draws power via the socket 304. The timing module 318 is configured to provide a timing signal to the microcontroller 312 in order for the microcontroller 312 to determine a particular period of time over which the voltage drop 324 occurs.

The microcontroller 312 is configured to store select portions of the measured electrical consumption information in the memory 110 as the electricity usage data 112. To illustrate, in the particular embodiment illustrated in FIG. 3, the microcontroller 312 may limit the amount of data stored in the memory 110 by storing the first electricity usage data 202 in response to a first measured voltage drop 324 (e.g., 120V) in association with a first time that may represent a time when the appliance is turned on. Further, the microcontroller 312 may limit the amount of data stored in the memory 110 by storing the second electricity usage data 204 in response to a second measured voltage drop 324 (e.g., 0V) in association with a second time that may represent a time when the appliance is turned off. In alternative embodiments, the microcontroller 312 may record the electricity usage data 112 at various levels of granularity.

FIGS. 1-3 illustrate a particular embodiment of a re-ordering device 102 that may not include an input device for a customer to identify the communication data 114. Accordingly, referring to FIG. 4, another electronic device 400 (i.e., an electronic device other than the re-ordering device 102) may allow the customer to provide the communication data 114 for storage in the memory 110 of the re-ordering device 102. FIG. 4 illustrates an example of a companion user interface 402 that may be presented on a display of the other electronic device 400 (e.g., a tablet computing device or a smartphone).

In the example of FIG. 4, the companion user interface 402 includes a first area 406 to provide an SSID, a second area 408 to enter a password (if applicable), and a selectable option 410 to save information to the re-ordering device 102. In some cases, the first area 406 may include a list of selectable SSIDs that may be able to provide a wireless connection. In the example of FIG. 4, the list of SSIDs includes a first SSID 414 (identified as “SSID(1)”), a second SSID 416 (identified as “SSID(2)”), up to an Nth SSID 418 (identified as “SSID(N)”). The customer may select the SSID 328 associated with the customer's WAP 116 (e.g., via a touchscreen or other input device). Further, the customer may provide the (optional) password 330 associated with the customer's WAP 116 via a text input box 420.

In response to selection of the selectable option 410 to save the information, the electronic device 400 may wirelessly communicate the SSID 328 and the (optional) password 330 to the re-ordering device 102 (e.g., via a Wi-Fi protocol). The re-ordering device 102 may store the SSID 328 and the (optional) password 330 in the memory 110 in order to allow the re-ordering device to establish a wireless connection with the customer's WAP 116.

Referring to FIG. 5, an alternative embodiment of a re-ordering device 502 in which select components described above may be built into a power outlet that includes a socket 504 to receive a power cord from an appliance and that is directly connected to an alternating current (AC) source 506 (e.g., that may provide e.g., a 120V or 240V voltage input). FIG. 5 further illustrates an example in which the re-ordering device 502 may include a selectable button 508 to enter a wireless configuration mode. FIG. 5 further illustrates a particular example in which the re-ordering device 502 may include a light 510 or other visual or audible feedback mechanism that may provide information to the customer regarding e.g., data being sent and/or received. That is, while FIGS. 1-5 illustrate data (e.g., the electricity usage data 112) being sent via the antenna 322 to the wireless access point 118, in some cases the antenna 322 may be configured to receive data and may initiate the illumination of the light 510 accordingly.

FIG. 6 illustrates an example process 600 for determining whether to automatically re-order item(s) to be delivered to a customer based on electricity usage data received from a re-ordering device, as described above. FIG. 6 illustrates the process 600 as a collection of blocks in a logical flow diagram, which represents a sequence of operations, some or all of which can be implemented in hardware, software or a combination thereof. In the context of software, the blocks represent computer-executable instructions stored on one or more computer-readable media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described should not be construed as a limitation. Any number of the described blocks can be combined in any order and/or in parallel to implement the process, or alternative processes, and not all of the blocks need be executed. For discussion purposes, the processes are described with reference to the architectures and environments described in the examples herein, although the processes may be implemented in a wide variety of other architectures or environments.

At 602, the process 600 includes receiving electricity usage data from a re-ordering device of a customer. For example, referring to FIGS. 1 and 2, the analysis module 124 may receive the electricity usage data 112 from the re-ordering device 102.

In the particular embodiment illustrated in FIG. 6, the process 600 includes determining a type of appliance that is electrically connected to the re-ordering device based on the electricity usage data, at 604. For example, referring to FIGS. 1 and 2, the analysis module 124 may compare the electricity usage data 112 to a plurality of signatures 208 stored in the electrical signature database 130. In the example of FIG. 1, the appliance 104 is a washing machine. Accordingly, referring to FIG. 2, the analysis module 124 may determine that the electrical usage data 112 matches the first signature 210 and that the appliance type 228 is a washing machine. In alternative embodiments, the user may specify the appliance type. Further, in some cases, a default option may be to determine the type of appliance unless the system receives the information (e.g., from the user, from the appliance, or from the re-ordering device, among other alternatives).

At 606, the process 600 includes determining, based on order history information for the customer, an estimated remaining quantity of one or more items that are associated with the appliance type. For example, referring to FIG. 2, the customer module 126 may determine, based on the order history information 230, an estimated remaining quantity of the detergent 238 and the dryer sheets 240.

At 608, the process 600 includes comparing the estimated remaining quantity of item(s) to one or more thresholds. For example, referring to FIG. 2, the re-order module 128 may compare the estimated remaining quantity of the detergent 238 to a first threshold and may compare the estimated remaining quantity of the dryer sheets 240 to a second threshold.

At 610, the process 600 includes determining whether one or more thresholds are satisfied. When the threshold(s) are satisfied, the process 600 includes decrementing the estimated remaining quantity of item(s), at 612. For example, referring to FIG. 2, the re-order module 128 may determine that the estimated remaining quantity of the detergent 238 satisfies the first threshold and may decrement the estimated remaining quantity of detergent. As another example, referring to FIG. 2, the re-order module 128 may determine that the estimated remaining quantity of the dryer sheets 240 satisfies the second threshold and may decrement the estimated remaining quantity of dryer sheets.

When the threshold(s) are not satisfied, the process 600 includes generating order data for automated re-ordering of item(s) to be delivered to the customer, at 614. For example, referring to FIGS. 1 and 2, the re-order module 128 may generate the order data 138 for automated re-ordering of the item(s) 148 to be delivered to the customer.

As indicated above, the order in which the operations are described in the example of FIG. 6 should not be construed as a limitation. Any number of the described blocks can be combined in any order and/or in parallel to implement the process, or alternative processes, and not all of the blocks need be executed.

FIG. 7 illustrates an example process 700 for providing communication data for storage in a memory of a re-ordering device using a companion user interface presented via a display of another electronic device, as described above. FIG. 7 illustrates the process 700 as a collection of blocks in a logical flow diagram, which represents a sequence of operations, some or all of which can be implemented in hardware, software or a combination thereof. In the context of software, the blocks represent computer-executable instructions stored on one or more computer-readable media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described should not be construed as a limitation. Any number of the described blocks can be combined in any order and/or in parallel to implement the process, or alternative processes, and not all of the blocks need be executed. For discussion purposes, the processes are described with reference to the architectures and environments described in the examples herein, although the processes may be implemented in a wide variety of other architectures or environments.

In the particular embodiment illustrated in FIG. 7, the process 700 includes receiving a selection of a setup button on a re-ordering device, at 702. For example, referring to the embodiment of the re-ordering device 502 illustrated in FIG. 5, a user may select the setup button 508. The process 700 includes entering a wireless configuration mode, at 704. In alternative embodiments, the re-ordering device may enter the wireless configuration mode upon first use. For example, referring to the embodiments of the re-ordering device 102 illustrated in FIGS. 1-4, the re-ordering device 102 may enter the wireless configuration mode when plugged into the power outlet 106 for the first time.

At 706, the process 700 includes receiving wireless connection information from a customer. For example, the re-ordering device may not include an input device to allow the customer to provide wireless connection information such as an SSID and password. Accordingly, a companion application user interface may be presented on a display of another device (e.g., a smartphone), and the customer may provide the wireless connection information via the companion application user interface.
